No, that is simply not true. You conveniently ignore how long the Meccans tolerated his weirdness. He lived with then for 10 years after he anointed himself a prophet and it was only after he began to attract followers that the Meccans became uneasy with his relentless preaching. You have to remember he was telling them, non-stop, for about a decade, that paganism was a great sin and that its followers were in for quite some fun in the Hellfire which he described in withering detail to anyone who would listen. His persecution was richly deserved.
What is your source of this information as we know none of us were there to verify it so one either listens to the Muslims version or those who believe Islam is false?
My source is Baha'u'llah Whom I recognise as the Promised One foretold in all the Holy Books.
Now if He is that Holy One then His version is right. People can accept whichever version suits their bias but the real truth can only be verified by another Messenger of God Who has infallible knowledge on the matter.
If people don't believe in a God Who sends Prophets with infallible knowledge then you cannot claim your version of 1400 years ago to be absolutely correct as there is no way for you to or anyone to verify it and historians only give their version not necessarily the truth or accurate account so how can you be so sure when you weren't an eye witness and I know many famous western writers throughout the centuries have openly been biased against Muhammad and written derogatory things which from my source are completely false
As I said, for me I can be sure because I rest my case on Baha'u'llah.
I'll post some things He said about Muhammad later.
